Answer 2

$\sf \huge \underline{answer} \implies$

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.

It is a vector quantity, possessing a magnitude and a direction.

If m is an object's mass and v is its velocity (also a vector quantity),

then the object's momentum is: =m.

In SI units, momentum is measured in kilogram meters per second (kg⋅m/s).
